Solution Overview

Problem

Slide-type mobile communication terminals face challenges in mounting and detaching memory cards without increasing thickness, as existing methods either require battery removal or result in the card protruding externally, leading to damage and aesthetic issues.

Innovation Solution

A receiving recess is formed on the rear surface of the slide cover with guides to securely mount the memory card, and a socket connects it electronically to the main PCB, allowing easy mounting and detachment without increasing the terminal's thickness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the memory card is mounted to the rear part of the main body, then the memory card can be mounted, but the battery must be detached and the thickness of the main body is increased

Engineering Contradiction:

Improvememory card mountingVSAvoidthickness of main body

Core Design Contradiction:

Ease of operationVSLength of stationary object

Solution Approach 1:

The patent divides the terminal into two functional parts: the main body (containing battery and processing units) and the slide cover (containing LCD screen and memory card mounting). This segmentation allows the memory card to be mounted on the slide cover without affecting the main body's thickness or requiring battery removal.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transitions from mounting the memory card in the main body (depth dimension) to mounting it on the slide cover's rear surface (external surface dimension). This dimensional shift enables memory card mounting without increasing the main body's thickness.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the memory card is inserted into the side surface of the main body, then the memory card can be mounted, but the terminal appearance is spoiled and the memory card is prone to damage

Engineering Contradiction:

Improvememory card mountingVSAvoidmemory card damage risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The slide cover acts as an intermediary structure between the main body and the memory card. It provides a protected mounting location for the memory card on its rear surface, shielding the card from external damage while maintaining accessibility.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The memory card is nested within a receiving recess formed on the rear surface of the slide cover. This nested structure allows the memory card to be securely housed while remaining accessible, preventing both aesthetic degradation and physical damage.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Length of stationary object

If the memory card is mounted on the slide cover, then the terminal thickness is maintained, but the receiving recess must be formed without increasing thickness

Engineering Contradiction:

Improveterminal thicknessVSAvoidreceiving recess formation

Core Design Contradiction:

Length of stationary objectVSEase of manufacture

Solution Approach 1:

The patent applies local quality by forming a receiving recess only on the rear surface of the slide cover where the memory card will be mounted, rather than modifying the entire main body structure. This localized approach maintains overall terminal thickness while providing the necessary mounting functionality.

Inventive Principle:

Principle #3Local quality

AI summary

Disclosed is a slide-type mobile communication terminal capable of mounting a memory card, wherein the memory card can be easily mounted/detached and a mounted state of the memory card can be stably maintained while minimizing a thickness increase of the terminal due to the mount of the memory card, by forming a receiving recess for mounting the memory card on a rear surface of a slide cover.
